I just noticed that my AC has begun acting very weird. The AC doesnt work until my car starts running for about 5 minutes. If I sit idle the AC blows warmer air at me until the car is going for about 5 more minutes. If I am driving steady the AC works wonderfully until I stop again. Its a repeat cycle. I have never had this problem until recently. Its not as if the AC doesnt work. It just doesnt work until I start driving for 5-10 minutes. Is this normal? I don't think so. How and where do I take it to fix it?

Thanks,

Ryan
